CVE-2022-50643

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel’s Common Internet File System (CIFS) implementation within the cifs copy file range() function. Specifically, a transaction ID (xid) leak can occur when a file is used by swap. If the file is in use by swap, the function should free the xid before returning an error, but it fails to do so, resulting in a leaked xid.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
